2. Wind Blows Wind is the result of pressure differences between two areas Air moves from an area of higher pressure toward an area of lower pressure The greater the difference in pressure, the stronger the wind. Pressure differences are normally created by the uneven heating and cooling of the air

3. General Description Wind energy is a form of energy that uses wind turbines to convert the kinetic energy of the wind into other forms of energy. Either mechanical energy for grinding grain or pumping water or electrical energy to power homes, schools, and so on. Wind energy can produce about 50 to 300 kilowatts of electricity each.

4. How it Works The blades of the turbine are attached to a hub that is mounted on a turning shaft which goes through a transmission box where the speed is continually increased. The transmission box is attached to a high speed shaft which turns on a generator that makes electricity. Winds have to be above 12 to 14 mph The turbine has a brake that keeps the blades from turning too fast and being damaged.

5. Advantages Ample, abundant supply Widely distributed, readily available around the globe Cheapest way to produce energy on a large scale Generates no pollution, reduces toxic gas emissions Can benefit economy in rural areas since the turbines can be built on farms and ranches. A large number of turbines have to be built to produce large amounts of energy Turbines create a large amount of noise Cannot be predicted Non dispatch able, cannot be stored Requires higher investment Disadvantages  Positives & Negatives

6. Wind Potential Greatest potential for land based wind power in the Midwest. Greatest potential for off shore wind power located on the pacific shore.

7. Wind Power Around the World Wind energy mostly generated out of Germany and USA. Top 10 countries that can use wind power are Germany, Denmark, USA, Spain, India, china, Portugal, France, Italy, and the United Kingdom.
